The information in this datasheet is intended to illustrate the operation and completeness of the information contained in this datasheet nor grant any license to. I will connect a voltage divider to the input of the ADC to measure the voltage. Even an inexpensive TL will be okay at maximum conversion rate.

Remember to filter and decouple with a RC circuit if you do not have a separate Vref regulator such as the 78L You can go as low as 1. The Varef pin has high impedance when datasheft converter is not operating, however it draws 30pC typically per conversion. Have you examined the code-spread caused by external noise sources that couple into your sensor, or into your wiring between sensor and ADC, or into your ADC IC?
Page 38 of datasheet shows a VREF pin. I see no mention of internal reference in the Table of Contents. Sign up using Email and Password. There is a paper discussing this, for a thermistor of Kohm; check on robustcircuitdesign.
Datzsheet could use the supply voltage however that is usually a pretty crude and noisy reference source. A reasonable choice would be an external 2.
